MBTA to quiz rail car maker on delays

Wants answers to delivery delay

Frustrated state officials have summoned to Boston the chief executive of a South Korean company lagging far behind on a $190 million contract to build commuter rail coaches, demanding to know how the firm can avoid additional delays that would leave riders relying on cramped, dated rail cars.

Already nearly two years late, Hyundai Rotem appears to be in danger of falling further behind on its contract to build 75 coaches, officials said. The modern double-decker cars are supposed to replace some of the MBTA’s oldest single-level cars and expand the size and reliability of its 410-coach commuter rail fleet.
